Referring more in` detail to thei drawings;- they embodiments chosen to. illustrate: the inventionarev shown as comprising. a-rinmber off Wa1lsegments, such as side.vvallusegnfientsv4 l,. 2, 31 and li which are alike or identical or counterpart in structure and which` are interchangeably placed; end walls 5. and 6, also alike, are identical' or' counterpart in structure and' which are interchangeably placed; top'- Wall'- segments and 8,

also alike orf-identical or counterpart in-'structurefand which are interchangeably placed-; and bottom Wall segments@` and lill, also-'alike oridentic'al or counterpart in structure and Whic-h are inter'-v changeably placed'. Y

The top wall segments T-- preferably-'have openings with like or identicaldoo'rs H, I`2,"v i3 and MT similarly placed, see Figure land also Figure-v 3. The bottom wall segments-l 9'-If preferably have longitudinallydisposed drain ol'i'annelsl5 and I6 also arranged inv similar or counterpart; location. These channels may have; as. at the'V ends thereof, suitable drain outiet's; i1 and" i3); and shown by Wayof example in Figure 3. l3ntAL these drain outlets may be locatedjat any point' along the channels I5- andl (iy as desired'andlfbund' to be most useful'.- videdtransversewall segments; |95 and/2U', see'lFigL ure 2, so as to provide chambers 2i' and iwhich" are to serve as a chamber.' for" a refrigerating power unit, and the otherV chamber; for a deep' freeze reirigerating chamber; Betweenv these' segments is provided.another'chamber 23 which` serves as a regular refrigeratinggchamber'. segments I9 and 2i! have doors2d`and25to afford'.

Within thestru-cture are` p ro These.

terial, the edge portions of which `are adapted to overlap the end parts of the wall segments` 9 and I0. About the zbody of the core 34 is an enclosing plate 38 the sides of which are adapted to press seal with insulating material 31 of sheet form or the like and interposed between the biased ends of the segments 9 and I0 and the sides of the plate 38. The edges of the plate 36 'may be fixed or connected to the plate 35 as desired, as by welding or the like. Through the segment 33 extends a bolt 38 which has a threaded'end to receive a nut 39 and which passes through a hub 40 of a cross bolt 4I The opposite ends of this cross bolt are threaded to receive nuts 42 and also extend through posts or studs 43 which are suitably xed to the segments 9 and I0. By vtightening the nuts 39'and 42 the segment 33 is tightly abutted and sealed'with the ends of the walls 9 and I9, and also the side ends are pulled toward each other to tightly abut and seal with the segment 3,3. Referring to Fig. 6,V it will be seen that the ends of the segment 33 are formed, as with a stepped or biased joint 44, to t with the lower or upper end of the doors 25 and 28 or 2l and 29, as the case might be.

Where wall segments meet in a dihedral angle, as shown in.'l1"ig. 7 by way of illustration, the meeting end portions of the segments, such as an end segment 6 or "I, and a side-segment I or 2, by way of example, there is interposed a preferably flat insulating sheet 45, and about the corner is placed an angular plate 46, the edge portions of which-overlap the end parts of the wall segments Yi Aor 2 and 6 or l, as shownin Fig. 7. Along the inside is provided a similar plate 4l. Theiiange portions Vof `these plates 46k and 4l, as also the Vend portions of the wall segments areprovided with suitable holes forV the passage therethrough of bolts 48 and 49. vThe the plates 4S and 4l toward each other to clampv the end parts of the wall sections I or 2, and

6 or l, and also to tightly seal with the sealing sheet 45. If desired additional clamping may behad by way of lugs 52 and 53 of which the lug 52 may be rigid with the plate '47 and-the lug 53 may be secured to a segment, as segment I or 2as shown, by way of a suitable securing element 54, such as a screw or bolt, and these lugs 52 and 53 are suitably provided with holes for the passage therethrough of a bolt 55 threaded to receive a nut 59. By tightening this nut the end portions of the segments I or? and S or l' will be tightly pulled utogetlrier.Y

At the trihedral angle corners, such as where a top or bottom wall segment, and end wall segment, Yand a sidewall segment meet, a similar clamping means may be used as shown in Fig.

4 8. In this case there is provided an outer trihedral angle cap or corner plate 5l and an inner similar plate 58 and these plates have apical holes 59 and 60 for the passage of a bolt 6I which is threaded to receive a tightening nut 62 and a Washer 63, as shown. The bolt, it .will be understood, may also pass through the insulating sheets interposed between the corner end portions of the three Wall segments joined at such corner.

While I have herein described and upon the drawings shown an illustrative form of the invention, it is to be understood that the invention is not limited thereto but comprehends other constructions, details, arrangements of parts, features, and the like'without departing from the spirit of the invention. A A Y Having thus disclosed the invention, I claim: 1. A refrigerator structure comprising side, end, topand bottom walls, said top and bottom walls each formed of at least two segments, means for uniting the two segments each of the top and bottom walls, said means including a core of Vinsulating material of trapezoidal cross sectional form, the joining ends of the two segments each of the top and bottom walls being biased and conforming to the shape and .size of said insulating core, and means carried by said core and cooperating with other means carried by each of said top and bottom wall segments for holding and sealing saidcore imposition.

2. A refrigerator structureV comprising side, end, top and bottom walls, said top and bottom walls each formed ofat least two segments, means for uniting Vthe two segmentsV each of the topA and bottom walls, said means including a core of insulating material of trapezoidal cross sectional form, the joining ends of the two segments each of the top and bottom walls being biased andrconforming to the shape and size of said insulating core, a bolt having one end secured in said core and extending vertically there-- through with its other end disposed Vwithin the refrigerator structure, a second bolt extending longitudinally from one of said segments to the other within said structure, said first bolt passing through said second bolt at right angles thereto, and fastening means on the ends of said bolts for clamping and sealing said core in posiion.
